Description

Technical Field

[0001] The present invention relates to the field of welding, and more particularly to seamless welding equipment. Background Art

[0002] Induction welding is a form of seamless welding that utilizes the skin effect and proximity effect generated by high-frequency current to join steel plates and other metal materials. Induction welding involves placing one or more turns of an induction coil around the steel pipe being welded. Multiple turns provide better results than a single turn, but multi-turn coils are more difficult to manufacture and install. A smaller distance between the induction coil and the steel pipe surface results in higher efficiency, but this can easily cause discharge between the coil and the pipe. Generally, a gap of 5 to 8 mm is recommended. Since the induction coil does not contact the steel plate, wear is eliminated. The induced current is relatively stable, ensuring weld stability. This results in excellent surface quality and smooth welds. Induction welding is widely used in the production of high-precision pipes, such as API pipes. Currently, manual clamping of the two welded components is required during induction welding, which wastes manpower. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a seamless welding device, which has the beneficial effect of automatically clamping welded parts.

[0004] A seamless welding device includes a rotating seat, a slider I and a slider II. The two sliders I are symmetrically placed in the rotating seat, and the slider II is located below the two sliders I. The lower parts of the two sliders I are respectively integrally formed with triangular notches, and the upper side of the slider II is integrally formed with a triangular protrusion. The protrusion on the slider II complements the notches below the two sliders I. The slider II is nested inside the rotating seat and slides up and down inside the rotating seat.

[0005] It also includes ridges, slide grooves, guide rails and springs. The two ridges are integrally formed on the front and rear sides of the slider I. The two slide grooves are symmetrically integrally formed on the front and rear sides of the rotating seat corresponding to the two ridges. The guide rail is integrally formed on the left side of the slider I. The two springs are respectively nested on the outside of the two guide rails symmetrically placed on the slider I, and the two springs are respectively welded to the inside of the rotating seat.

[0006] It also includes a discharge rod, which is welded to the front side of the slider II.

[0007] It also includes a bracket II and a hydraulic rod I. The four rotating seats are fixed to the bracket II in the four directions of up, down, left and right by bolts respectively. The large ends of the four hydraulic rods I are fixed to the front side of the bracket II by bolts.

[0024] like Figure 3-5 As shown, this example can achieve the effect of clamping weldment Ⅰ.

[0025] The seamless welding equipment includes a rotating seat 201, a slider I 202, and a slider II 205. The two sliders I 202 are symmetrically placed within the rotating seat 201, and the slider II 205 is positioned below the two sliders I 202. The lower portions of the two sliders I 202 are each integrally formed with a triangular notch, and the upper portion of the slider II 205 is integrally formed with a triangular protrusion. The protrusion on the slider II 205 complements the notch below the two sliders I 202. The slider II 205 is nested within the rotating seat 201 and slides up and down within the rotating seat. When the slider II 205 moves upward within the rotating seat 201, the two sliders I 202 symmetrically placed within the rotating seat 201 are squeezed to the sides by the slider II, thereby achieving a loosening function. When the slider II 205 moves downward within the rotating seat 201, the two sliders I 202 symmetrically placed within the rotating seat 201 move toward the center, thereby achieving a clamping function, thereby achieving the function of clamping the weldment I.

[0026] like Figure 3-5 As shown, this example can achieve the effect of resetting the slider Ⅰ 202.

[0027] Since the seamless welding equipment includes ridges 204, grooves 206, guide rails 203 and springs 207, the two ridges 204 are integrally formed on the front and rear sides of the slider I 202, the two grooves 206 are symmetrically integrally formed on the front and rear sides of the rotating seat 201 corresponding to the two ridges 204, the guide rail 203 is integrally formed on the left side of the slider I 202, the two springs 207 are nested on the outside of the two guide rails 203 symmetrically placed on the slider I 202, and the two springs 207 are welded to the inside of the rotating seat 201. The slider I 202 moves left and right in the rotating seat 201 through the ridges 204 and the grooves 206. When the slider II 205 moves upward in the rotating seat 201 and squeezes the two sliders I 202, the two sliders I 202 move left and right respectively through the ridges 204 and the grooves 206, and the two springs 207 nested on the guide rail 203 are squeezed. The springs 207 are squeezed and compressed along the axial direction of the guide rail 203. When the slider II 205 moves downward in the rotating seat 201, the squeezed springs 207 on both sides give the two sliders I 202 an inward elastic force, and the slider I 202 is reset along the grooves 206, thereby achieving the effect of resetting the slider I 202.

[0028] like Figure 3-5 As shown, this example can achieve the effect of removing weldment I.

[0029] The seamless welding equipment includes a stripper rod 208, the left end of which is welded to the front side of slider II 205. The right end of the stripper rod 208 is located to the right of the rotating base 201 and between the two sliders I 202. When slider II 205 moves upward, the two sliders I 202 separate, thereby releasing the clamped weldment I. At the same time, slider II 205 drives the stripper rod 208 forward, pushing the welded material away from the equipment, thereby removing the weldment I.

[0030] like Figure 3-7 As shown, this example can achieve the effect of automatically clamping weldment Ⅰ.

[0031] Since the seamless welding equipment includes a bracket II 301 and a hydraulic rod I 302, the four rotating seats 201 are respectively fixed to the upper, lower, left and right sides of the bracket II 301 by bolts, thereby achieving the effect of fixing the rotating seat 201. The large ends of the four hydraulic rods I 302 are respectively fixed to the front side of the bracket II 301 by bolts, and the small ends of the four hydraulic rods I 302 are respectively fixedly connected to the bottom of the four sliders II 205 corresponding to the four rotating seats 201 by threads. The left hydraulic rod I 302 extends, thereby pushing the left slider II 205 to move left, thereby pushing the two sliders I 202 on the left to separate, thereby achieving the effect of automatically loosening the weldment I. The left hydraulic rod I 302 retracts, thereby pulling the left slider II 205 to move right, and then the two sliders I 202 on the left return to their original position under the elastic force of the spring 207, thereby achieving the effect of clamping the weldment I, thereby achieving the effect of automatically clamping the weldment I.

[0032] like Figure 8 As shown, this example can achieve the effect of positioning and clamping weldment I.

[0033] Since the seamless welding equipment includes a bracket I101, a rotating wheel 401, a positioning groove 402 and a card slot 209, the bracket II301 is rotatably connected to the right part of the bracket I101, and multiple concentric card slots 209 are integrally formed at the end of the unloading rod 208. The left part of the bracket I101 is integrally formed with a support, and threaded shafts are integrally formed on both sides of the rotating wheel 401. Two nuts are threaded on both sides of the shaft. The rotating wheel 401 is fixed to the support on the left part of the bracket I101 through two nuts and the threaded shaft, and the positioning groove 402 is integrally formed inside the rotating wheel 401. The positioning groove 402 is composed of holes with gradually decreasing diameters connected together. When welding parts I of different diameters need to be welded, the nut is loosened and the wheel 401 is adjusted so that the welding part I is concentric with the slot 209 after passing through the wheel 401, and the nut is tightened to fix the wheel 401, thereby achieving the positioning of welding parts I of different diameters; after the welding part I passes through the wheel 401, it is clamped on the slot 209 of the appropriate diameter, and then the effect of positioning the welding part I is achieved by simultaneously positioning the wheel 401 and the slot 209. After the welding part I is positioned, the hydraulic rod I 302 is retracted and the welding part I is pushed forward at the same time, and then the two sliders I 202 clamp the welding part I, thereby achieving the effect of positioning and clamping the welding part I.

[0034] like Figure 9 As shown, this example can achieve the welding effect.

[0035] The seamless welding equipment includes hydraulic rod II 104 and induction coil 105. Hydraulic rod II 104 is bolted to the upper portion of bracket I 101, and induction coil 105 is bolted to the lower portion of hydraulic rod II 104. The center of induction coil 105 is concentric with the center of slot 209 fixed to the upper side of bracket II 301. When the clamped weldment I rotates below induction coil 105, hydraulic rod II 104 extends, driving induction coil 105 downward, simultaneously inserting weldment II into weldment I. This triggers the skin effect and adjacent effect of the induction coil, welding weldments I and II together, achieving the desired weld quality. After welding, the hydraulic rod II 104 is retracted, thereby driving the induction coil 105 to move upward, and then the rotating bracket II 301 rotates the welded part to the left, and then the hydraulic rod I 302 is extended, thereby driving the slider II 205 to move to the left, and then the two sliders I 202 release the welded part. At the same time, the slider II 205 moving to the left drives the unloading rod 208 to move to the left, thereby removing the welded material, thereby completing the welding process.

[0036] like Figure 9-10 As shown, this example can achieve the effect of providing weldment II.

[0037] The seamless welding equipment includes a bracket III 501 and a conveyor belt 502. Bracket III 501 is bolted to the upper side of bracket I 101, and conveyor belt 502 is rotatably connected to the upper portion of bracket III 501. Numerous welded parts II are placed on conveyor belt 502, which continuously moves welded parts II above induction coil 105, thereby providing welded parts II.

[0038] like Figure 9-10 As shown, this example can achieve the effect of controlling a welding part II to move above the induction coil 105.

[0039] Since the seamless welding equipment includes baffle I 503, baffle II 504 and block 505, baffle I 503 is fixed to the upper side of the conveyor belt 502 by bolts, the end of baffle I 503 gradually narrows, and arc-shaped grooves are integrally formed on both sides of the end of baffle I 503. Baffle II 504 is slidably connected to the arc-shaped groove at the end of baffle I 503 through bearings. Block 505 is welded to the upper side of baffle I 503. The position of block 505 is in the middle part of baffle I 503, and the lower end of block 505 is spaced from the conveyor belt 502. Many welding parts II pass through the block 505 when moving on the conveyor belt 502, and then the vertically moving welding parts II continue to move, and the horizontally moving welding parts II collide with the block 505 and change to vertical movement, thereby achieving the effect of unifying the direction of welding parts II; the front end of the baffle I 503 gradually narrows, thereby achieving the effect of only one welding part II moving to the front end of the bracket III 501 at the same time; the baffle II 504 blocks the welding part II from continuing to move forward, and when the rotating seat 201 rotates to the bottom of the induction coil 105, the baffle II 504 rises, and then the welding part II moves forward to the end of the conveyor belt 502 and then falls. After one welding part II falls, the baffle II 504 falls and continues to block the welding part II that continues to move forward, thereby achieving the effect of controlling only one welding part to move to the top of the induction coil 105 at the same time.

[0040] like Figure 9 As shown, this example can achieve the effect of positioning welding part II.

[0041] Since the seamless welding equipment includes funnel 102 and positioning hole 103, funnel 102 is welded to the upper portion of bracket I 101, located below baffle I 503. Positioning hole 103 is welded below funnel 102, located above and concentric with induction coil 105. After falling from the end of conveyor belt 502, welded part II is oriented by funnel 102 and then positioned by positioning hole 103, thereby achieving the desired positioning effect. After the positioning, welded part II then falls onto welded part I for welding.

[0042] like Figure 1-9 As shown, this example can achieve the effect of seamless welding equipment rotation.

[0043] Since the seamless welding equipment includes motor I106 and motor II506, motor I106 is fixed to the rear side of bracket I101 by bolts, motor I106 rotates to connect bracket II301 and drives bracket II301 to rotate, and then bracket II301 rotates, and then the rotating seat 201 on bracket II301 rotates, thereby realizing the welding process of the seamless welding equipment; motor II506 is fixed to the upper part of bracket I101 by bolts, motor II506 is connected to baffle II504 through lever rotation, and then motor II506 rotates clockwise to drive the lever to descend, and then drives baffle II504 to descend, thereby achieving the effect of blocking welding part II, motor II506 rotates counterclockwise, and then drives the lever to rise, and then drives baffle II504 to rise, and then welding part II moves forward through conveyor belt 502, and then falls from the end of conveyor belt 502.
